Instructions

Implementation Reference

• src/mcp/hostname.ts:16-27 (handler)

  The anonymous async handler function that implements the core logic of the 'get_hostname' tool. It calls getHostname() to retrieve the system hostname and returns it formatted as MCP text content.
  async () => { // Note: Error handling is simplified; the MCP SDK handles basic errors. // More complex tools might still need try/catch. const hostname = getHostname(); return { content: [{ type: "text", // Return plain text for simple values text: hostname }] }; }
• src/mcp/hostname.ts:12-29 (registration)

  The registerHostnameTool function that registers the 'get_hostname' MCP tool on the server, specifying the tool name, description, and handler function.
  export function registerHostnameTool(server: McpServer): void { server.tool( "get_hostname", "Returns the hostname of the machine running the MCP server.", async () => { // Note: Error handling is simplified; the MCP SDK handles basic errors. // More complex tools might still need try/catch. const hostname = getHostname(); return { content: [{ type: "text", // Return plain text for simple values text: hostname }] }; } ); }
• src/mcp/hostname.ts:8-10 (helper)

  Helper utility function that retrieves the hostname using Node.js 'os' module.
  export function getHostname(): string { return os.hostname(); }
• src/index.ts:19-19 (registration)

  Invocation of registerHostnameTool during server initialization, effectively registering the tool.
  registerHostnameTool(server);
